No need to get pissy. It's not likely the quality of the converter. I'm guessing an incomplete job by your trans shop. When a trans or converter fails and pollutes the system with clutch materials there is a procedure that must be followed or the trans will fail again. Often between 1,000 & 10,000 miles.
Here it goes. The trans lines (item 7) must be removed and flushed repeatedly in both directions with radiator cleaner.
The cooler bypass (item 8)must be removed, disassembled and cleaned.
The trans cooler remove and discard. The ports inside are to small and it can never be flushed completely clean. Materials will remain inside and dislodge later while under use due to heat and pressures thus polluting the system again.
The radiator should also be replaced but if money is tight it is possible to flush it using the same procedure as on the lines.
Lastly an inline trans filter should be installed and changed every 10,000 miles. Rockauto carries them. Run $10. Heres a pic of where I installed mine. Made it easy.
